Monitoring PostgreSQL on Win32

A very common question from Win32 users is how to monitor Postgres the same way you can do with ps on Unix. There's a simple trick to it - don't use Task Manager, use Process Explorer from Sysinternals. So why is this. For comparision, here is a snapshot of my laptop with PostgreSQL running, and just a single client connection:

The same processes, as seen from Process Explorer:

The most obvious difference - you can now see the process tree. You will see pg_ctl that is the service manager, that it started the postmaster, and that which subprocesses the postmaster started. You will also see the only second level postgres.exe, which is part of the stats system.

You will also notice in the Handle list, that there is an Event named pgident: .... This event contains the information you would find in the ps output on Unix and identifies the individual PostgreSQL process.

So - simply using a different tool gives you a lot more information. For 8.2 there will be some additional win32 management stuff, but more aobut that somewhere else.
